i don't know if the 2015 update even applies to cranks, or if its just shifters/derailleurs.

obviously, i'm inquiring about 11-speed.

Pretty sure the <2015 Chorus crank arms weren't hollow - they had some kind of foam core.

R/SR were hollow, plus the usual addition of different bearings / Ti spindle.

2015+ I'm 99% sure there is no difference whatsoever in the crank arms between C/R/SR.

Only super record has the time spindle. Record has the usb bearings and super record had cult bearings.

any significant weight difference between the chorus and the record due to the foam core?

There is like a 30 gram difference between the two.
